[0002] The main shaft system assembly and connection device of a large wind turbine generator set can be used for connection work to realize the docking and fixing of the drive structure and the driven structure, so that when the drive structure is running, the driven structure can be controlled to adjust and perform power transmission.
[0003] However, the current assembly and connection devices for the main shaft system of large wind turbine generator sets have the following problems: they are not convenient for rapid positioning, cannot be quickly aligned, and are inconvenient to install, and need to be improved. Utility Model Content
[0004] The purpose of this invention is to provide an assembly and connection device for the main shaft system of a large wind turbine generator set, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a main shaft system assembly and connection device for a large wind turbine generator set, comprising a drive transmission structure and a driven transmission structure, wherein the drive transmission structure and the driven transmission structure are docked and limited to transmit power.
[0006] The drive transmission structure is used to connect with the power structure. The gear plate rotates, which drives the hydraulic seat, docking limit shaft and adapter rod to rotate, thus realizing power transmission. The spring rod and contact block are pressed to perform hydraulic control, so that the docking limit shaft can be extended and retracted on the hydraulic seat.
[0007] The driven transmission structure is adapted to the driving transmission structure and is connected to the limiting shaft through the limiting pin bracket to drive the first link and the second link to rotate.
[0008] Specifically, the drive transmission structure includes a gear plate, a hydraulic seat, and a docking limit shaft. The hydraulic seat is fixedly connected to the side end of the gear plate, and the docking limit shaft is telescopically connected to the hydraulic seat. The hydraulic seat is connected to the pressure connecting seat. The contact block moves on the pressure connecting seat through a spring rod. By squeezing, the pressure connecting seat is driven to move, thereby squeezing the oil in the hydraulic seat and controlling the telescopic adjustment of the docking limit shaft.
[0009] Specifically, an adapter rod is fixedly connected to the front center of the hydraulic seat, and an adapter groove is provided on the adapter rod. The adapter rod is movably connected to the pressurized connecting seat.
[0010] Specifically, the driven transmission structure includes a limiting pin frame and a mating plate. The limiting pin frame is threaded onto the mating plate, a first connecting rod is fixedly connected to the side end of the mating plate, and a second connecting rod is fixedly connected to the side end of the first connecting rod.
[0011] Specifically, the docking plate is provided with a groove block that matches the adapter groove.
[0012] Specifically, when the adapter rod is engaged with the docking plate, the docking plate presses against the contact block, causing the contact block to move through the spring rod and drive the pressure connecting seat to move. The spring rod and the contact block constitute a buffer unit.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. By installing a drive transmission structure, power transmission can be achieved. When the gear plate rotates, it can drive the hydraulic base and the docking limit shaft to rotate, and at the same time drive the adapter rod to rotate. The drive transmission structure and the driven transmission structure are connected and limited through the docking limit shaft and the adapter rod. When the drive transmission structure rotates, it can drive the driven transmission structure to rotate, thereby achieving the purpose of power transmission.
[0015] 2. By installing the contact block, the contact block can apply pressure, which drives the spring rod to compress, and then pushes the pressure connecting seat to move. The pressure connecting seat is connected to the hydraulic seat in a limit telescopic connection. Through the movement of the pressure connecting seat, the oil in the hydraulic seat can be squeezed, causing the docking limit shaft to extend on the hydraulic seat, so that the docking limit shaft docks with the docking plate. Then, the limit pin frame is screwed to connect the screw on the limit pin frame with the groove on the docking limit shaft, thereby limiting and locking the drive transmission structure and the driven transmission structure, thereby improving the connection stability and facilitating rapid docking.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a large wind turbine generator main shaft system assembly and connection device, including a drive transmission structure 1 and a driven transmission structure 2, wherein the drive transmission structure 1 and the driven transmission structure 2 are docked and limited to transmit power.
[0023] The drive transmission structure 1 is used to connect with the power structure. The gear plate 3 rotates, which drives the hydraulic seat 4, docking limit shaft 5, and adapter rod 6 to rotate, thereby realizing power transmission. The spring rod 9 and contact block 10 are pressed to perform hydraulic control, so that the docking limit shaft 5 can be extended and retracted on the hydraulic seat 4.
[0024] The driven transmission structure 2 is adapted to the drive transmission structure 1 and is connected to the limiting shaft 5 via the limiting pin frame 11, thereby driving the first connecting rod 13 and the second connecting rod 14 to rotate.
[0025] The drive transmission structure 1 includes a gear plate 3, a hydraulic seat 4, and a docking limit shaft 5. The side end of the gear plate 3 is fixedly connected to the hydraulic seat 4, and the docking limit shaft 5 is telescopically connected to the hydraulic seat 4. The hydraulic seat 4 is connected to the pressure connecting seat 8. The contact block 10 moves on the pressure connecting seat 8 through the spring rod 9. By squeezing, the pressure connecting seat 8 is driven to move, thereby squeezing the oil in the hydraulic seat 4 and controlling the telescopic adjustment of the docking limit shaft 5.
[0026] An adapter rod 6 is fixedly connected to the front center of the hydraulic base 4. An adapter groove 7 is provided on the adapter rod 6. The adapter rod 6 is movably connected to the pressurized connecting seat 8. By installing the drive transmission structure 1, power transmission can be carried out. When the gear plate 3 rotates, it can drive the hydraulic base 4 and the docking limit shaft 5 to rotate, and at the same time drive the adapter rod 6 to rotate. The drive transmission structure 1 and the driven transmission structure 2 are connected and limited through the docking limit shaft 5 and the adapter rod 6. When the drive transmission structure 1 rotates, it can drive the driven transmission structure 2 to rotate, thereby achieving the purpose of power transmission.
[0027] The driven transmission structure 2 includes a limiting pin frame 11 and a docking plate 12. The limiting pin frame 11 is threaded onto the docking plate 12. A first connecting rod 13 is fixedly connected to the side end of the docking plate 12, and a second connecting rod 14 is fixedly connected to the side end of the first connecting rod 13. By installing a contact block 10, the contact block 10 can be pressurized, causing the spring rod 9 to compress, and then pushing the pressurizing connecting seat 8 to move. The pressurizing connecting seat 8 is in a limited telescopic connection with the hydraulic seat 4. Through the movement of the pressurizing connecting seat 8, the oil in the hydraulic seat 4 can be squeezed, causing the docking limiting shaft 5 to extend on the hydraulic seat 4, so that the docking limiting shaft 5 docks with the docking plate 12. Then, the limiting pin frame 11 is screwed to connect the screw on the limiting pin frame 11 with the groove on the docking limiting shaft 5, thereby limiting and locking the drive transmission structure 1 and the driven transmission structure 2, thereby improving the connection stability and facilitating rapid docking.
[0028] The mating plate 12 is provided with a groove block that is compatible with the adapter groove 7.
[0029] When the adapter rod 6 is engaged with the docking plate 12, the docking plate 12 presses against the contact block 10, causing the contact block 10 to drive the pressure connecting seat 8 to move through the spring rod 9, and the spring rod 9 and the contact block 10 constitute a buffer unit.
[0030] Working principle: When needed, the user places the driven transmission structure 2 on the side of the drive transmission structure 1, and the mating plate 12 and the adapter rod 6 are matched and connected. The slot on the mating plate 12 cooperates with the adapter slot 7 to limit the push, so that the drive transmission structure 1 and the driven transmission structure 2 reach the appropriate position. At this time, the mating plate 12 will push the contact block 10 to move, so that the contact block 10 is squeezed by the spring rod 9, and then drives the pressure connecting seat 8 to move. The pressure connecting seat 8 moves on the hydraulic seat 4, which can perform the squeezing work, so that the hydraulic pressure is... The retraction pushes the docking limit shaft 5 to extend on the hydraulic seat 4. At this time, the docking limit shaft 5 is inserted into the docking plate 12 and aligned with the limit pin frame 11. Then, the limit pin frame 11 is screwed so that the screw on the limit pin frame 11 and the groove on the docking limit shaft 5 are connected and limited, realizing the limiting work of the drive transmission structure 1 and the driven transmission structure 2. At the same time, the first connecting rod 13 and the second connecting rod 14 are connected to the external driven structure for the purpose of power transmission. The pressure connecting seat 8 and the adapter rod 6 only move relative to each other and are not directly connected, thus completing the work.
